As shown in fig. 1 and 2, according to an embodiment of the present utility model, a slag sweeping curtain 1 is applied to a slag conveyor, the slag conveyor includes a frame 2 and a scraper 4, and the scraper 4 is movable relative to the frame 2. The slag curtain 1 comprises: a main shaft 11 and a plurality of slag sweeping assemblies 12. The main shaft 11 extends along a first direction, the main shaft 11 is suitable for being mounted on the frame 2, a plurality of slag sweeping assemblies 12 are sequentially arranged on the main shaft 11 along the first direction, the slag sweeping assemblies 12 comprise a connecting plate 121 and a flexible plate 122, one end of the connecting plate 121 is pivotally connected with the main shaft 11, the other end of the connecting plate 121 is connected with the flexible plate 122, and the flexible plate 122 is suitable for being abutted against the working surface of the scraping plate 4 so as to clean the working surface of the scraping plate 4.
According to the slag sweeping curtain 1 provided by the embodiment of the utility model, when the slag on the scraping plate 4 is swept, as the slag sweeping assemblies 12 are multiple and the slag sweeping assemblies 12 are all independently and pivotably connected with the main shaft 11, different areas of the scraping plate 4 can be swept by different slag sweeping assemblies 12, and free rotation is not interfered with each other, so that the cleaning effect of the scraping plate 4 is improved. On the other hand, the flexible plate 122 is arranged on the slag sweeping component 12, so that the resistance of the scraping plate 4 to pass through can be reduced, and the normal operation of the slag dragging machine is not affected. Therefore, the slag sweeping curtain 1 of the embodiment of the utility model can clear ash on the scraping plate 4, has less interference on the scraping plate 4 and has better cleaning effect.
It is understood that the slag sweeping assembly 12 may be two or more. The specific number of the slag sweeping assemblies 12 can be selected according to the length of the scraping plate 4, and the utility model is not limited to the specific number. For example, in the embodiment of the present utility model, the number of the slag sweeping assemblies 12 is three, and the three slag sweeping assemblies 12 are arranged on the main shaft 11 at equal intervals.
In some embodiments, as shown in fig. 1, the connection plate 121 includes a movable sleeve 1212 and a plate body 1211, the movable sleeve 1212 is sleeved on the main shaft 11 and is rotatable relative to the main shaft 11, one end of the plate body 1211 is connected to the movable sleeve 1212, and the other end of the plate body 1211 is connected to the flexible plate 122. It is understood that the movable sleeve 1212 is pivotally sleeved on the main shaft 11 and can freely rotate. For example, the angle of rotation of the movable sleeve 1212 may be 0-180 degrees.
In one example, plate 1211 is a rigid plate and flexible plate 122 is a rubber plate. The plate 1211 is an iron plate, and since the plate 1211 is a rigid plate, the structural strength of the slag sweeping assembly 12 can be improved, the slag blocking effect of the slag blocking curtain can be ensured, and the service life of the slag blocking curtain can be prolonged.
Alternatively, as shown in fig. 1, the plate 1211 is fixedly connected to the movable sleeve 1212, and the plate 1211 is detachably connected to the flexible plate 122. For example, the plate 1211 may be welded to the movable sleeve 1212, so that the connection strength between the plate 1211 and the movable sleeve 1212 may be improved, and the service life of the slag sweeping assembly 12 may be prolonged. The plate body 1211 is detachably connected with the flexible plate 122, and when the flexible plate 122 is worn to a certain extent, the flexible plate 122 can be independently removed and replaced, so that the later maintenance cost of the slag curtain 1 is reduced.
For example, as shown in FIG. 1, the slag sweeping assembly 12 further includes a screw 123, the screw 123 passing through the plate body 1211 and being threadedly engaged with the flexible plate 122. Further, the number of the screw members 123 may be plural, and the plural screw members 123 are disposed on the plate body 1211 at intervals along the axial direction of the main shaft 11, so that the stability of the connection of the plate body 1211 and the flexible plate 122 can be ensured, and the assembly and the disassembly are convenient, and the later maintenance work is facilitated.
In some embodiments, as shown in fig. 1, the slag curtain 1 further includes a fixing sleeve 13, and the fixing sleeve 13 is sleeved on the end of the main shaft 11 and is adapted to be connected with the frame 2. For example, there are two fixing bushings 13, and two fixing bushings 13 are respectively installed at both ends of the main shaft 11 to mount and dismount the slag curtain 1.
As shown in fig. 1 and 2, a slag conveyor according to another embodiment of the present utility model includes: the slag sweeping curtain 1 comprises a frame 2, a chain assembly 3, a scraping plate 4, a slag sweeping curtain 1 and a chain assembly 3, wherein the scraping plate 4 is arranged on the frame 2, the scraping plate 4 is connected with the chain assembly 3, the chain assembly 3 is used for driving the scraping plate 4 to move along a preset direction, the slag sweeping curtain 1 is the slag sweeping curtain 1 provided by the slag sweeping curtain 1, the slag sweeping curtain 1 is arranged on the frame 2, and the scraping plate 4 sequentially passes through the slag sweeping curtain 1 in the operation of the slag extractor, so that ash adhered on the working surface of the scraping plate 4 is cleaned to a slag hopper again.
According to the slag conveyor of the embodiment of the utility model, when slag on the scraping plate 4 is cleaned, as the slag sweeping assemblies 12 are multiple and the slag sweeping assemblies 12 are independently and pivotably connected with the main shaft 11, different areas of the scraping plate 4 can be cleaned by different slag sweeping assemblies 12, and the slag sweeping assemblies can freely rotate without interference, so that the cleaning effect of the scraping plate 4 is improved. On the other hand, the flexible plate 122 is arranged on the slag sweeping component 12, so that the resistance of the scraping plate 4 to pass through can be reduced, and the normal operation of the slag dragging machine is not affected. Therefore, the slag sweeping curtain 1 of the slag extractor of the embodiment of the utility model can clean ash on the scraping plate 4, has less interference on the scraping plate 4 and has better cleaning effect.
It can be understood that the main shaft 11 is inserted into the fixed shaft sleeve 13 and then welded on the inner walls of the two sides above the return section of the frame 2 to approach the slag hopper. Three movable shaft sleeves 1212 are respectively arranged in the main shaft 11, each movable shaft sleeve 1212 is welded to a corresponding plate 1211, the total length of the three slag sweeping assemblies 12 is equal to the total length of the scraping plate 4, and in order to avoid rigid collision between the slag sweeping assemblies 12 and the working surface of the scraping plate 4, a flexible plate 122 made of rubber is arranged at the lower end of the plate 1211 and is fixed on the plate 1211 by bolts, so that the wear resistance and the softness of the slag sweeping curtain 1 can be ensured, and slag sweeping can be more thoroughly.
